6b4b6601 - [X86] Move -x86-use-vzeroupper command line flag into runOnMachineFunction for the pass itself rather than the pass pipeline construction

Sat, 13 Jun 2020 21:40:56 +0000

[X86] Move -x86-use-vzeroupper command line flag into runOnMachineFunction for the pass itself rather than the pass pipeline constructionThis pass has no dependencies on other passes so conditionallyincluding it in the pipeline doens't do much. Just move it thepass itself to keep it isolated. List of files: /llvm-project-15.0.7/llvm/lib/Target/X86/X86VZeroUpper.cpp

b2b6a54f - [X86] Add support for -mvzeroupper and -mno-vzeroupper to match gcc

Mon, 04 Nov 2019 18:20:00 +0000

[X86] Add support for -mvzeroupper and -mno-vzeroupper to match gcc-mvzeroupper will force the vzeroupper insertion pass to run onCPUs that normally wouldn't. -mno-vzeroupper disables it on CPUswhere it normally runs.To support this with the default feature handling in clang, weneed a vzeroupper feature flag in X86.td. Since this flag hasthe opposite polarity of the fast-partial-ymm-or-zmm-write weused to use to disable the pass, we now need to add this newflag to every CPU except KNL/KNM and BTVER2 to keep identicalbehavior.Remove -fast-partial-ymm-or-zmm-write which is no longer used.Differential Revision: https://reviews.llvm.org/D69786 List of files: /llvm-project-15.0.7/llvm/lib/Target/X86/X86VZeroUpper.cpp

f8804047 - [X86] Use VR512_0_15RegClass intead of VR512RegClass in X86VZeroUpper.

Wed, 25 Sep 2019 23:25:15 +0000

[X86] Use VR512_0_15RegClass intead of VR512RegClass in X86VZeroUpper.This pass is only concerned with ZMM0-15 and YMM0-15. For YMMwe use VR256 which only contains YMM0-15, but for ZMM we wereusing VR512 which contains ZMM0-31. Using VR512_0_15 is morecorrect.Given that the ABI and register allocator will use registers inorder, its unlikely that register from 16-31 would be usedwithout also using 0-15. So this probably doesn't functionallymatter.llvm-svn: 372933 List of files: /llvm-project-15.0.7/llvm/lib/Target/X86/X86VZeroUpper.cpp

2946cd70 - Update the file headers across all of the LLVM projects in the monorepo

Sat, 19 Jan 2019 08:50:56 +0000

Update the file headers across all of the LLVM projects in the monorepoto reflect the new license.We understand that people may be surprised that we're moving the headerentirely to discuss the new license. We checked this carefully with theFoundation's lawyer and we believe this is the correct approach.Essentially, all code in the project is now made available by the LLVMproject under our new license, so you will see that the license headersinclude that license only. Some of our contributors have contributedcode under our old license, and accordingly, we have retained a copy ofour old license notice in the top-level files in each project andrepository.llvm-svn: 351636 List of files: /llvm-project-15.0.7/llvm/lib/Target/X86/X86VZeroUpper.cpp

d34e60ca - Rename DEBUG macro to LLVM_DEBUG.

Mon, 14 May 2018 12:53:11 +0000

Rename DEBUG macro to LLVM_DEBUG. The DEBUG() macro is very generic so it might clash with other projects.The renaming was done as follows:- git grep -l 'DEBUG' | xargs sed -i 's/\bDEBUG\s\?(/LLVM_DEBUG(/g'- git diff -U0 master | ../clang/tools/clang-format/clang-format-diff.py -i -p1 -style LLVM- Manual change to APInt- Manually chage DOCS as regex doesn't match it.In the transition period the DEBUG() macro is still present and aliasedto the LLVM_DEBUG() one.Differential Revision: https://reviews.llvm.org/D43624llvm-svn: 332240 List of files: /llvm-project-15.0.7/llvm/lib/Target/X86/X86VZeroUpper.cpp
